Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clamping tool used for clamping objects such as cloth and leather.

Examples of such holding tools include paper scissor clips and fountain pen clips;

Previous gripping tools generally had complex structures and were often thick. It is called a gem clip and is made by bending a wire several times as a simple and thin gripping device.
However, this clip had the disadvantage that the clamping force was low and it was difficult to attach it to a plate-shaped base material or the like.

In view of the above-mentioned circumstances, the present invention was made for the purpose of providing a clamping tool that has a relatively simple structure, can be kept thin, and has a high clamping force, and is characterized by: A plate-shaped pedestal and a plate-shaped presser are rotatably connected in a hinged manner by a shaft part provided on one side and a support part provided on the other side. A clamping tool configured to hold an object between a base and a presser, the joint end of either one of the base and the presser having a plurality of cuts extending from the end toward the middle part. is separated into a plurality of parallel strips, and at least one of these strips is an elastic piece that bends like a cantilever when subjected to an external force, and the other strips are formed into a shaft portion or a coupling device. The other of the pedestal and the holding device is provided with a coupling tool on the opposite side that is coupled to the coupling tool, and a coupling tool is provided on the other side of the support section and the other of the pedestal and the holding tool, and a coupling tool is provided on the opposite side to be coupled to the coupling tool, and a coupling tool is provided on the opposite side to be connected to the elastic piece and to clamp the article from the elastic piece. The point is that a protruding piece that receives reaction force is provided. An embodiment shown in one drawing will be described below.

FIGS. 1 and 2 are explanatory diagrams of one example of a clamping tool according to the present invention, and this clamping tool 6' is a base material (
In the illustrated example, it is used by being attached to a hard core plate which corresponds to the back side of the patch cloth 7 and is arranged parallel to the cloth. The clamping tool 6' is 1. As shown in FIG. 2, there is provided a pedestal 11 fixed to the base material and a presser 1.2 pivotally connected to the pedestal 11. Two cuts 1'la are made up to the middle part.

Therefore, the upper end portion of the base 11 is separated into a total of three strips: the elastic piece 11b and the connecting pieces 11C located on both sides of the elastic piece 11b. A gutter-shaped support portion lid is provided at the tip of the connecting piece 11C.
is set and 0.

At the joint end of the presser 12, there is a shaft portion 12C that extends left and right.
A protruding piece 12a that comes into contact with the elastic piece 11b of the pedestal is provided. This shaft portion 12C is a gutter-shaped support portion l of the pedestal.
id, and these shaft parts 12C1 support parts lid
The base 11 and the presser 12 are rotatably coupled by the elastic piece 11b. In addition, a claw 12 is provided in the middle part of the presser 12 to firmly fix the material to the fabric to be clamped.
b- is provided. FIGS. 2(b) to 2(d) are side views showing the open state, the closing state, and the closed state of this clamping tool, respectively, and as can be seen from the figures,
During the rotation stroke of the presser 12, the elastic piece 11b is bent by the protruding piece 12a, and is fixed in both the closed state and the open state by the action of the elastic piece 11b.

Figure 3 and below show examples that are different from the previous example.
As shown in FIGS. 3 and 4, this clamping tool 6 also includes a base 11 and a holding tool 12, as in the previous example. In this example, four cuts 11a are provided at the joint end of one pedestal 11, thereby separating the end into five strips.

Elastic pieces 11b and llb are provided on both sides of the wide connecting piece 11C, which is the central strip, and small and medium connecting pieces IIC' and 11(:' are further provided on the outside of both elastic pieces. There is a protruding piece 12 at the joint end of the presser 12.
Two sets of coupling members (A) each consisting of a combination of a and a shaft portion 12C are provided in parallel. The protruding pieces 12a of the two sets of coupling members (A) are provided at positions facing both the elastic pieces 11b of the pedestal 11, and one of the shaft parts protruding left and right from the base of each protruding piece 12a is located at the center. - to the support part lid of the connecting piece 11C, and the other to the support part 1 of the outer connecting piece 11C'.
1d', respectively. In this example, the connecting member (
A) are provided at two locations with an interval between them, so the looseness of the joint is small and operational stability is good. In this example, press.

The bait 12 is bent approximately 120 degrees at the connection part.
Even when the presser 12 is superimposed on the base 11 (closed state), the protruding piece 12a or the elastic piece 11b is maintained in a somewhat pressed state. Therefore, the clamping force is increased, and even thin objects can be firmly clamped. Note that four claws 12b are provided.

6 and 7 show that this clamping tool 6 is attached to a hard base material 20.
The pedestal 11 made of a metal plate is fixed to a base material 20 also made of a metal plate by caulking (C). In this way, if this clamping tool is fixed to a hard base material and attached to the base material or a desired object for use, the taste base material overlaps the elastic piece 11b and backs it up. , the reaction force that the presser 12 receives becomes correspondingly larger, making it possible to hold the object more strongly. Also,
Since the base material has a larger area than the pedestal, it becomes easy to press the pedestal side when opening and closing the clamping tool, and there is an advantage that the opening and closing operation becomes extremely easy.

Note that the clamping tool and the base material can be made of a metal material, a synthetic resin material, or the like.

As is clear from the above description, the clamping tool according to the present invention does not require a coil spring or the like for applying clamping pressure.
It is structurally simple and the overall thickness can be reduced.

Furthermore, when in use, the object is held using the elasticity of the elastic piece provided integrally with the pedestal or the presser, so the clamping force is high and the holding is reliable. If a plurality of such clamping tools are used by arranging them in parallel on a hard base material, the opening/closing operation becomes easier, the clamping force is increased, and the practicality is further improved.

[Also, it is preferable to coat the holding tool 12 of the clamping tool with a synthetic resin coating such as a rubber material, since this improves the tactile sensation during opening and closing operations and improves the aesthetic appearance. When this covering material is a rubber material, the coefficient of friction increases, so that sufficient clamping force can be obtained without providing the claws 12b. In this case, the outer surface (the surface that becomes the outside when closed) of the presser 12 may be covered with a secondary coating of a different coating material such as decorative leather. Figures 8(a) and 8(b) and the following figures show an embodiment in which the above-mentioned coating is applied.
A coating layer 25 of synthetic rubber (for example, NBR) is formed on both the inner and outer surfaces of the cover. The metal base 12' of the presser 12 has a plurality of window-shaped holes 26, 26, . . . (8 in the illustrated example).
The coating layers 25 on both the inner and outer surfaces pass through these holes 26 and are integrally joined to each other. For this reason, the coating layer 25
is firmly fixed to the metal base 12' of the presser 12''. Since the coating material cannot be baked onto a stainless steel plate, it is preferable to adopt this fixing method. Leather 27 is provided on the surface of the coating layer 25.
is applied as a secondary coating layer to improve aesthetic appearance. Furthermore, minute protrusions 28 are alternately formed on both the inner and outer surfaces of the coating layer 25, and the protrusions 28 on the inner surface enhance the clamping effect, and the protrusions 2B on the outer surface increase the adhesive strength of the leather 27. ing. It is appropriate that the dimensions of the protruding stripes be approximately 0.5 m in height and 0.5 m in width. 9, (a), (''b) and 10 (a).
